Default Connect ps/2 to EXP8661

Hi,

I want to experiment with an old computer but the manual of the
motherboard isn't so good.

It's an EXP8661 motherbord, you can see the layout at:
http://stason.org/TULARC/pc/motherbo...m-EXP8661.html.

So the MS1 is the ps/2 mouse connector were I have the put in my
counter. The connector on the motherboard has 4 pins and the counter
has 5 holes and one of them hasn't got a wire. So it's like no wire,
yellow one, blue one, red one, green one.

Can anyone help me connecting it?
BTW: can I do something wrong by connecting it wrong?

You most likely need a PS/2 connector that mounts into one of openings
in your chassis for expansion cards. Here's an example that has a
parallel port *and* a PS/2 port:

With a bit more of a search, you can probably find one that just has a
mouse port.

I've got already an ps/2 poert but I don't know how to connect it to
my motherboard.

What sort of connector is attached to the port?

I don't recall, if I ever knew, what the typical color
coding for a PS2 port dongle was. You have vcc (power),
ground, data, and clock lines.

With a multimeter you can determine which pin is power by 5V
when the system is on (meter ground being system ground
anywhere). With the meter the ground pin will have
practically zero resistance to case ground. With data and
clock, if you get them reversed it won't work, just switch
the two around and try again.

Similar for the dongle itself, by looking at a pinout for a
PS2 port, you can use the meter to check continuity to
confirm which pins in the socket each connector pin
corresponds to.

Found a manual here. MS1 is "DATA,DATA,GND,VCC" :-)
Don't know what happened to the CLOCK signal.

I don't have a multimeter.

So the lines are data, data ground, vcc.

Should I connect it like this: yellow wire (data), blue wire (data),
red wire (ground), green wire (vcc)
Or: green wire (data), red wire (data), blue wire (ground), yellow
wire (vcc)

And the hole with no wire is for nothing?

Data, clock, vcc (5V), ground

(not necessarily in that order)

red wire (ground), green wire (vcc)

wire (vcc)

The hole with no wire is for nothing, but I cannot advise on
whether to leave the other wires in the positions they are
in, or swap them. You need to determine which wires
correspond to which PS2 port pins on the dongle, and which
motherboard pins are vcc and ground. Without a
diagram/manual to tell you, using a multimeter is important.

If you connect it wrong it might damage a keyboard connected
to it.

You can get a cheap one with about 5 dollars and a trip to Radio
Shack. Do so.

OK, the manufacturer says it is data, data, ground, vcc.

It is either

clock, data, ground, vcc

or it is

data, clock, ground, vcc

According to this page, the data and clock are open collector,
so you should be able to try either wiring pattern and see
if it works. They also include a couple diagrams for
DIN connector wiring.
